I have two ovens. In one I put 3 Honey Buns and one Carrot Cake, in the other 4 Carrot Cakes. One Bun Dough was already in the cold oven for some time. I lit both ovens and waited. I know, that Buns only need one branch, while Cakes need two, so I waited until the buns were ready, so they won't get burned.
Now to the bug: When I wanted to take out the buns, the cake in that oven was ready too! The cakes in the other oven however took the whole 2 branches.
